I have a brand new still in the box flowmaster muffler still in the box, if youre interested. 40 series. My buddy has it in his truck and souunds awesome, so i bought one but then i changed my mind cause i dont want to mess with the stock legal roush exhaust my truck came with. it is not as loud as the flowmaster but im guessing ill get used to it.

 

I went with a 3" spacer in the front and a 1 1/2" add a leaf (for added payload) in the rear. Cost was @ $200 total and @ an hour and a half of my time.
